What You'll Learn
Lubricating the gears
First, identify the location of the gears. They are typically found under a shield or a top plate with a few screws holding it in place. Remove the shield or top plate to access the gears. If your jack has a bushing at the front, don't forget to lubricate it as well.
Once you have accessed the gears, it's time to choose the right lubricant. Grease is a common choice for trailer jack lubrication as it lasts longer. White lithium grease is a good option and can be applied with a grease gun or by hand if you don't have access to one. If you prefer a spray lubricant, look for a product like motorcycle chain lube, which leaves behind a viscous and long-lasting coating.
Apply the grease or lubricant generously to the gears, ensuring full coverage. Pay attention to the nooks and crannies, as these areas may require extra lubrication. If your jack has a Zerk grease fitting, make sure to take advantage of it during lubrication.
After applying the lubricant, reassemble the jack by replacing the shield or top plate. Tighten any screws or bolts that were removed during the process. It is important to ensure that the components are securely fastened to prevent any issues during operation.
Finally, test the jack to ensure it is operating smoothly and efficiently. Crank the jack to see if the lubrication has improved its performance. If you notice any issues or unusual noises, recheck the lubrication and ensure that all components are properly secured.

Grease vs. spray lubricant
When it comes to lubricating an electric trailer jack, you have a few options: grease or spray lubricant. Grease is a mixture of soap blended with vegetable or mineral oil and has a high level of viscosity, allowing it to adhere well to surfaces. Lithium-based greases, in particular, are suitable for metal-on-metal lubrication and can withstand a wide range of temperatures. They also offer rust protection and reduce friction and wear. White lithium grease is also water-resistant and suitable for equipment exposed to harsh weather conditions.
On the other hand, spray lubricants are easier to apply and can reach narrow gaps. Silicone spray lubricants, for example, can be used on multiple surface types, including rubber, and are water-resistant. However, they are not suitable for high-temperature applications.
If you are lubricating a trailer jack with a gearbox, grease is ideal. However, if you are unable to remove the shield, a spray lubricant can be used. For jacks with accessible gears, white lithium grease can be used, and the shaft can be sprayed with a silicone spray.
When deciding between grease and spray lubricant, consider the temperature range, the material of the jack, and the ease of application. Both options will help reduce friction and wear on your trailer jack, ensuring smooth operation.

Using a grease gun
To grease an electric trailer jack using a grease gun, you will need to first identify the grease fitting or grease nipple on the jack. This is usually located on the lower stem assembly of the jack, near the bottom. Once you have located the grease fitting, extend the jack until the fitting is aligned with the hole in the outer tube.
Now, you can attach your grease gun to the fitting and begin pumping grease into the jack. It is recommended to use two pumps of grease from a standard grease gun to ensure the jack is sufficiently lubricated. If your grease gun has a variable output pressure, be sure to set it to the appropriate level for the task.
In addition to greasing the jack screw, you may also need to grease the gears of the electric trailer jack. To do this, first remove the fuse from the fuse holder and then remove the gear cover, which is typically held in place with four Phillips screws. Once the gear cover is removed, you can use your grease gun to apply chassis lube to the gears. Be sure to apply grease liberally to all moving parts of the gears to ensure smooth operation.
After greasing the gears, reinstall the gear cover and replace the fuse in the fuse holder. It is important to note that the specific steps for greasing an electric trailer jack may vary slightly depending on the make and model of your jack, so be sure to consult your owner's manual or a qualified technician if you have any questions or concerns.

Lubricating the jack operator
To lubricate the jack operator, you will need to access the gears and apply a suitable lubricant.
First, locate the gears of the jack operator. These are typically found under a shield or cover, which may be secured with screws. Remove the shield and set it aside, being careful not to lose any small parts.
Once the gears are exposed, you can begin the lubrication process. It is recommended to use grease for this purpose, as it tends to last longer than other lubricants. Apply a small amount of grease to each gear, ensuring that they are thoroughly coated. You can use a brush or your finger to apply the grease, but be sure to wear gloves if using your finger to avoid getting grease on your hands.
In addition to the gears, you may also need to lubricate other components of the jack operator, such as the bushing and the hole through which the shaft passes. To do this, you may need to remove the shaft and apply grease directly to these areas. Make sure to follow any specific instructions provided by the manufacturer of your electric trailer jack.
After lubrication, remember to reassemble any parts that were removed and ensure that they are securely fastened. Test the jack operator to ensure that it is functioning smoothly and efficiently. Regular lubrication of the jack operator will help maintain the performance of your electric trailer jack and extend its lifespan.
